The invention relates to the technical field of support mortar, and more specifically, to a support mortar grouting material. In view of the conflict between the flowability requirement and the early strength requirement of the support mortar grouting material, the stabilizer and other raw materials are selected to solve the problem of its flexural strength, and the quick hardening cement, silica fume, early strength agent and high strength agent are used to solve the problem of its compressive strength, and the retarder and early strength agent are used. The setting time of stabilization period is determined by mixing strength agent and stabilizer. The raw materials used in the invention have excellent fluidity, no need of mechanical vibration and plastering, gravity grouting, self-leveling, compact filling template, no stratification, no segregation, rapid strength growth and rapid demoulding. The mortar grouting material can be used only by mixing raw materials in production and mixing in proportion with water during construction. The technology is simple and harmless to human body. The cementing material is 10% less than the existing products, which can reduce environmental pollution in raw materials and construction, and reduce the cost by 15%.

一种支座砂浆灌浆料
本专利技术涉及支座砂浆
,更具体而言,涉及一种支座砂浆灌浆料。
技术介绍
高速铁路安全、舒适、快速的运行,对路基的稳定、桥梁的刚度、轨道的平顺提出了更高的要求,因此路基、桥梁、轨道结构与一般铁路干线存在很大不同。短工期、严安全、高标准给具有承上启下作用、保证桥梁安全的支座的安装材料极高的要求。支座砂浆具有超早强性能。良好的膨胀填充性能、后期强度不倒缩是安全、耐久的重要保证。砂浆的高流动性和超早强在某种意义上来讲是矛盾关系,凝结时间、早期抗折抗压强度、后期抗压强度都是现有支座砂浆存在的问题。
